"It makes you feel a little better to be able to go outside and not worry about one of them running up, or them causing anyone else any problems," said Kayla Peterson's fiancee, Bill Bailey, the father of their child. "I think Kayla is up in heaven shining just a little brighter today because they were caught."

The supervisor of a U.S. Marshals task force said homicide suspect Marcus Velasquez and a 14-year-old conspiracy suspect were found late Tuesday night at the home of an "associate" on 34th Street. He said the boys were found through investigative work, not tips or help from relatives.

Marshals believe the suspects began moving from house to house after Peterson died. Police have not decided whether to filed charges against the people who gave the boys a place to stay.

A third suspect, 13-year-old boy, was already in custody on a conspiracy charge for the Dec. 8 incident that witnesses say began as Bailey left J's News on Seventh Avenue.

"My friend came in and got cigarettes, and three young kids followed him. They kept following him and asking him for a cigarette," said Brock Edwards, who was working at the convenience store.

Bailey said the teens followed him, harassing him while he walked the two blocks home to 13th Street. When he got there, Bailey said the 22-year-old Peterson came outside and told the boys to get a job.

"The next thing you know, they just pull out a gun and shoot for no reason. It was just over a cigarette," Edwards said. "Now, my friend lost his girlfriend -- an amazing, amazing girl, and she was such a good mother, too -- and now her child has to grow up without her mother being there."

He said trying to explain the situation to his daughter, Ellieonna, has not been easy: "I just tell her her mom was an angel and was taken away way too soon. She devoted her life to my daughter."

Bailey told Ingram he knows the suspects and played basketball with one of their fathers.

"These kids are very dangerous. They've already proven that they're dangerous, and we would like to see them off the streets as soon as possible," said Beaver Falls Police Chief Charles Jones. "Any time a life is taken, it's hard to deal with, but especially around the Christmas season, it's that much more difficult, especially when it's a young mother."

Kayla Peterson

Three teenagers were charged in connection with the senseless killing of Kayla Peterson, a 22-year-old mother who had some words for them as they harassed her boyfriend on a Saturday afternoon.

Boykin, who enters his fourth season, also wanted to clarify his comments on Sunday, a day after the Eagles traded him to the Steelers for a conditional fifth-round pick, stressing that his former head coach Chip Kelly is not a racist.
